1.18 Modular architecture
Series M panel meter are designed based on a modu -
lar architecture. This modularity allows to replacement,
change or add any of the internal modules conforming
the instrument.
Below is a graphical explanation of the location of each
module.
See section

for a list of optional modules available.
To open the housing and access the internal circuits, use
a flat screwdriver to unlock clips ‘D’, ‘C’, ‘B’ and ‘A’, in this
order. Remove the front filter. Let the inside of the instru -
ment slide out of the housing.
To reinsert the instrument make sure that all modules are
correctly connected to the pins on the display module.
Place all the set into the housing, assuring that the mod -
ules correctly fit into the internal guiding slides of the
housing. Once introduced, place again the front filter at
corner ‘X’, and then insert clips ‘A’, ‘B’, ‘C’ and ‘D’, in this
order.
Risk of electric shock. Removing the front
cover will grant access to the internal circuits.
Disconnect the input signal to prevent electric
shock to the operator. Operation must be per-
formed by qualified personnel only.
